lClaim. (01.116-135) In the rayon industry it is necessary that menoperating spinning machines designate thereon three facts in order thatthe table men or men removing silk from spinning boxes may knowinstantly the proper disposition to make of cakes thus removednamely,

1st is the cake regular. 2nd is the cake inferior. 3rd is the cakelight.

This is essential for the following reasons:

1st, it enables the table men to classify or grade the silk when removedfrom the spinning boxes placing regular or grade A silk in a certainclassification. 2nd, it enables them to place inferior silk in a secondclassification. 3rd, it enables them to place light cakes in a thirdclassification. And thereby eliminating the possibility of mixing orconfusing said classifications.

The present method used for this purpose in the rayon industry is themarking by chalk on or near the number corresponding to the can or boxcertain marks known to the table men.

Owing to the presence of water and steam in the spinning rooms andfurther owing to the fact that the men using the chalk, of a necessityare compelled to wear rubber gloves to protect their hands from acidsand owing to the fact that their hands are in this condition and thesemarkings are made on a wet rail, it necessarily blurs and dims the chalkmark. And when the men attempt to remove the chalk marks or signspreparatory to another doff these marks become very complex andconfusing, thereby making it impossible for the table men or other menwho are assigned to the duty of classifying the silk to place it in theproper classification.

Should any chalk, as frequently happens, be dropped on the spinningmachine and drawn by suction in the can or box, it ruins the silk ormakes it of an inferior quality.

This signal device being so designed and constructed that it may be madefrom various materials, in various sizes and colors, and so adaptable tohaving printing, engraving, stamping or coloring thereon which may beexposed or concealed. It is adaptable for use in any industry, businessor profession where it is necessary or expedient to communicateinformation from one person to another or as a reference for the partyoperating the same.

For these and many other reasons will appear the necessity of thisdevice as it is more fully hereinafter described in the followingspecifications and illustrated in the accompanying drawing and finallypointed out in the appended claim.

The above and other objects will appear and be better understood fromthe following description taken in connection with the accompanyingdrawing, in which:

Figure -1 is a front elevational view 'of the sliding indicator moved tothe'right.

Figure 2 is a similar viewwith the sliding indicator moved to the left.

Figure 3 is a side elevational view.

Figure 4 is a rear elevational view, showing the construction of thesliding indicator and holder, and 1 Figure 5 is a view similar to Figure4, but showing a slight modification.

Referring to the drawing by reference letters, it will be seen that myinvention consists of a substantially rectangular holder which may bemade of Bakelite, Celluloid, or other suitable material, and on whichholder may be printed, stamped, marked or engraved, any number, or otherindicia, as place used would necessitate, this numbered holder thereforeconstitutes one signal, as shown in Figure 1.

While I have shown in Figure l a holder provided with a certain numberit will be understood that I am not to be limited to this specificnumber, or lndicia, since the number, indicia', or size of holder maybediminished or increased as occasion requires. This holder A is to beattached to machine, box, drawer, shelf or any other place that it maybe used for signal purposes by nails, tacks, or screws through thecorners.

In Figure l I have shown a front elevation of holder A with slidingindicator B moved to a position to the right, exposing one end ofindicator, which may be painted, stamped, marked or engraved, with anyindicia, to make a separate signal, or it may have two or more colors orindicia,.to give two or more signals as occasion may require.

In Figure 2 I have shown a front elevation of holder A with slidingindicator B moved to a position to the left, exposing the left end ofsliding indicator which may be painted, stamped, marked or engraved withany indicia to make a separate signal or it may have two or more colorsor indicia to give two or more signals as occasion may require.

Figure 4 in drawing shows a rear elevation of signal device, showingback of holder A, construction of slidingindicator B which I haveprovided with actuating handle 0 to move sliding indicator from oneposition to another.

Stil1 referring to Figure4 it will be noticed I have provided holder Awith support or slide D upon which sliding indicator B moves from oneposition to another.

Figure 5 shows a slight modification in which the slide B is formed witha depending tooth I on its bottom edge for engaging any one of the threenotches 2v formed on the upper edge of the part D of the holder forholding the slide either in a central and neutral position or in asignaling position either at the right or left.

I have further provided this holder A with stops E which prevent slidingindicator from being moved beyond a certain point. I want to callparticular attention to sliding indicator B which I have provided withactuating handle C which extends above holder A to permit the moving ofslide from one position to another.

From the description of the invention thus far it will be apparent thatthis device is for attachment to a machine, desk, drawer, door, shelf orother place for signal purposes, that the number of signals would differon number of indicia or colors used.

Figure 3 in drawing shows a transverse view of device, showing holder A,sliding indicator B, sliding indicator handle C, support for slidingindicator D and stops for sliding indicator E.

As will be seen the support D is made in the form of a horizontallyextending rib on the rear face of the holder and at the bottom thereofwhile the stops E are made in the form of projections on the rear faceof the holder at the upper corners thereof.

Having thus described my invention as to construction 'and use, I claimand desire to have protected by Letters Patent:

A signal device of the class described comprising a holder havingidentifying indicia on its front face, the rear face being adapted to beconnected to a supporting member, said holder including a horizontallyextending rib on its rear face and at the lower part thereof having itsupper edge forming a horizontal shoulder and rearwardly extendingprojections at the upper corners of the rear face forming stop members,a slide member having its lower edge sliding on the shoulder and saidmember being of a length substantially that of the holder whereby whenthe slide member is in a central position in rear of the holder it willbe hidden from view by the holder, an upwardly extending handle formingpart connected with the upper edge of the slide member and centrallyarranged and projecting above the top of the holder, the junction of thehandle part with the slide member forming shoulders engaging the stopmembers for limiting outward movement of the slide member at either endof the holder, the ends of the slide member on the front face thereofbeing marked to form signal means each signal means being visible at anend of the device when the handle is engaging a stop member and saidstop members being of the same thickness as the rib, whereby said stopmembers and the rib will abut a supporting member to which the device isconnected, and means associated with the lower edge of the slide memberand the shoulder over which it slides for releasably holding the slidemember in either one of the projected positions or in a central neutralposition.
